The present invention relates to prodrugs of pyrazoline compounds, methods for their preparation, medicaments comprising these compounds as well as their use for the preparation of a medicament for the treatment of humans and animals.

Cannabinoids are compounds, which are derived from the cannabis sativa plant which is commonly known as marijuana. The most active chemical compound of the naturally occurring cannabinoids is tetrahydrocannabinol (THC), particularly Δ⁹-THC.

These naturally occurring cannabinoids as well as their synthetic analogues promote their physiological effects via binding to specific G-coupled receptors, the so-called cannabinoid-receptors.

At present, two distinct types of receptors that bind both the naturally occurring and synthetic cannabinoids have been identified and cloned. These receptors, which are designated CB₁ and CB₂ are involved in a variety of physiological or pathophysiological processes in humans and animals, e.g. processes related to the central nervous system, immune system, cardiovascular system, endocrinous system, respiratory system, the gastrointestinal tract or to reproduction, as described for example, in Hollister, Pharm. Rev. 38, 1986, 1-20; Reny and Singha, Prog. Drug. Res., 36, 71-114, 1991; Consroe and Sandyk, in Marijuana/Cannabinoids, Neurobiology and Neurophysiology, 459, Murphy L. and Barthe A. Eds., CRC Press, 1992.

Therefore, compounds, which have a high binding affinity for these cannabinoid receptors and which are suitable for modulating these receptors are useful in the prevention and/or treatment of cannabinoid-receptor related disorders.

In particular, the CB₁-receptor is involved in many different food-intake related disorders such as bulimia or obesity, including obesity associated with type II diabetes (non-insulin-dependent diabetes) and thus, compounds suitable for regulating this receptor may be used in the prophylaxis and/or treatment of these disorders.

Thus, it was an object of the present invention to provide novel compounds for use as active substances in medicaments. In particular, these active substances should be suitable for the modulation of cannabinoid receptors, more particularly for the modulation of cannabinoid 1 (CB₁) receptors.

Said object was achieved by providing the prodrugs of pyrazoline compounds of general formula I given below, their stereoisomers, corresponding salts and corresponding solvates thereof.

It has been found that these compounds have a high affinity for cannabinoid receptors, particularly for the CB₁-receptor, and that they act as modulators e.g. antagonists, inverse agonists or agonists on these receptors. They are therefore suitable for the prophylaxis and/or treatment of various disorders related to the central nervous system, the immune system, the cardiovascular system, the endocrinous system, the respiratory system, the gastrointestinal tract or reproduction in humans and/or animals, preferably humans including infants, children and grown-ups.

Thus, in one of its aspects the present invention relates to prodrugs of pyrazoline compounds of general formula I,

The respective description is hereby incorporated by reference and forms part of the disclosure. Reaction temperature as well as the duration of the reaction may vary over a broad range.

Preferred reaction temperatures range from −10° C. to the boiling point of the reaction medium. Suitable reaction times may vary for example from several minutes to several hours.

Preferably the reaction between a compound of general formula VI and general formula VII can also be carried out under acid catalysed conditions, more preferably by refluxing the above mentioned compounds in dichloromethane in the presence of copper(II) trifluoromethanesulfonate as described, for example, in Synlett, (1), 147-149, 2001.

This reaction preferably leads to racemates of compounds of general formula IV, wherein the phenyl substituent and R⁴ are located cis to one another on the pyrazoline ring. The respective enantiomers can be separated by conventional methods including chiral HPLC or resolution via the formation of diastereomeric salts and thus leading to compounds of general formula IV with an ee>99%. The configuration of compounds of general formula IV is maintained during the subsequent reaction steps, thus leading to enantiomerically pure compounds of general formula I (ee>99%).

Preferred reaction temperature range from 0° C. to the boiling point of the solvent and reaction times vary from several minutes to several hours.

The process is inter alia described in Drugs of the Future 1991, 16, 443; J. Med. Chem. 1987, 30, 2008; J. Med. Chem. 1989, 32, 2503; J. Org. Chem. 1978, 43, 4797; Tetrahedron Lett. 1977, 1571 and J. Pharm. Sci. 1968, 57, 774. The respective parts of description are hereby incorporated by reference and form part of the disclosure.

The afore mentioned reactions involving the synthesis of the 4,5-dihydro-pyrazole ring or the reaction of a compound comprising said ring are preferably carried out under an inert atmosphere, preferably under a nitrogen or argon atmosphere, to avoid oxidation of the ring-system.

During some synthetic reactions described above the protection of sensitive or reactive groups may be necessary and/or desirable. This can be performed by using conventional protective groups like those described in Protective groups in Organic Chemistry, ed. J. F. W. McOmie, Plenum Press, 1973; T. W. Greene & P. G. M. Wuts and Protective Groups in Organic Chemistry, John Wiley & sons, 1991. The respective parts of the description is hereby incorporated by reference and forms part of the disclosure. The protective groups may be eliminated when convenient by means well-known to those skilled in the art.

If the prodrugs of pyrazoline compounds of general formula I are obtained in form of a mixture of stereoisomers, particularly enantiomers or diastereomers, said mixtures may be separated by standard procedures known to those skilled in the art, e.g. chromatographic methods or crystallization with chiral reagents. It is also possible to obtain pure stereoisomers via stereoselective synthesis.

In a further aspect the present invention also provides a process for the preparation of salts of prodrugs of pyrazoline compounds of general formula I and stereoisomers thereof, wherein at least one compound of general formula I having at least one basic group is reacted with at least one inorganic and/or organic acid, preferably in the presence of a suitable reaction medium. Suitable reaction media include, for example, any of the ones given above. Suitable inorganic acids include hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, nitric acid, suitable organic acids are e.g. citric acid, maleic acid, fumaric acid, tartaric acid, or derivatives thereof, p-toluenesulfonic acid, methanesulfonic acid or camphersulfonic acid.

In yet a further aspect the present invention also provides a process for the preparation of salts of prodrugs of pyrazoline compounds of general formula I or stereoisomers thereof, wherein at least one compound of general formula I having at least one acidic group is reacted with one or more suitable bases, preferably in the presence of a suitable reaction medium. Suitable bases are e.g. hydroxides, carbonates or alkoxides, which include suitable cations, derived e.g. from alkaline metals, alkaline earth metals or organic cations, e.g. [NH_(n)R_(4-n)]⁺, wherein n is 0, 1, 2, 3 or 4 and R represents a branched or unbranched C₁₋₄-alkyl-radical. Suitable reaction media are, for example, any of the ones given above.

In the presence of several acidic or basic groups, mono- or poly-salts may be formed. Compounds of the formula I having an acidic group, for example a free carboxyl group, and a basic group, for example an amino group, may also be present in the form of inner salts, i.e., in zwitterionic form, or a part of the molecule may be present in the form of an inner salt and another part in the form of a normal salt.

Solvates, preferably hydrates, of the prodrugs of pyrazoline compounds of general formula I, of corresponding stereoisomers, of corresponding N-oxides or of corresponding salts thereof may also be obtained by standard procedures known to those skilled in the art.

Prodrugs of pyrazoline compounds of general formula I, which comprise nitrogen-atom containing saturated, unsaturated or aromatic rings may also be obtained in the form of their N-oxides by methods well known to those skilled in the art.

The purification and isolation of the inventive prodrugs of pyrazoline compounds of general formula I, of a corresponding stereoisomer, or salt, or N-oxide, or solvate or any intermediate thereof may, if required, be carried out by conventional methods known to those skilled in the art, e.g. chromatographic methods or recrystallization.

The prodrugs of pyrazoline compounds of general formula I given above, their stereoisomers, corresponding N-oxides, corresponding salts thereof and corresponding solvates are toxicologically acceptable and are therefore suitable as pharmaceutical active substances for the preparation of medicaments.

It has been found that the prodrugs of pyrazoline compounds of general formula I given above, stereoisomers thereof, N-oxides thereof, corresponding salts and corresponding solvates have a high affinity to cannabinoid receptors, particularly cannabinoid 1 (CB₁)-receptors, i.e. they are selective ligands for the CB₁-receptor and act as modulators, e.g. antagonists, inverse agonists or agonists, on these receptors. In particular, these pyrazoline compounds show little or no development of tolerance during treatment, particularly with respect to food intake, i.e. if the treatment is interrupted for a given period of time and then continued afterwards, the inventively used pyrazoline compounds will again show the desired effect. After ending the treatment with the pyrazoline compounds, the positive influence on the body weight is found to continue.

Furthermore, these prodrugs of pyrazoline compounds show relatively weak Herg channel affinity, thus a low risk of prolongation of the QT-interval is to be expected for these compounds.

In summary, the inventively used 4-substituted pyrazoline compounds are distinguished by a broad spectrum of beneficial effects, while at the same time showing relatively little undesired effects, i.e. effects which do not positively contribute to or even interfere with the well being of the patient.

Thus, an other aspect of the present invention relates to a medicament comprising at least one prodrug of pyrazoline compounds of general formula I including the aforementioned excluded compounds, optionally in form of one of its stereoisomers, preferably enantiomers or diastereomers, a racemate or in form of a mixture of at least two of its stereoisomers, preferably enantiomers and/or diastereomers, in any mixing ratio, or a corresponding N-oxide thereof, or a physiologically acceptable salt thereof, or a corresponding solvate thereof, and optionally at least one physiologically acceptable auxiliary agent.

The metabolic syndrome and definitions thereof are described in detail by Eckel et al., The Lancet, Vol. 365 (2005), 1415-1428, included herewith by reference. One of the respective definitions was established by the WHO in 1998 (as described in Alberti et al., Diabet. Med. 1998, 15, pages 539-53, the respective description thereof is herewith incorporated by reference and forms part of the present disclosure). The other, more widely accepted, definition of the metabolic syndrome was established by the Adult Treatment Panel (ATP III) of the US National Cholesterol Education Program (NCEP) in 2001, as described in JAMA 2001; 285; 2486-97, the respective description thereof is herewith incorporated by reference and forms part of the present disclosure.

The metabolic syndrome is characterized by an interaction of several physiological parameters such as triglycerides, lipids, blood pressure, glucose levels and insuline levels.

Even though obesity may play a critical role in the development of metabolic syndrome, many of its aspects are weight independent, especially some lipid parameters. Especially the positive influence on the weight independent aspects of the metabolic syndrome (see e.g. Pagotto and Pasquali, The Lancet, Vol. 365 (2005), 1363, 1364, included herewith by reference) like some blood parameters, especially lipid parameters is one of the major and surprising advantages of the inventively used substituted pyrazoline compounds.

Dementia is a disease characterized by the progressive deterioration in cognitive and social adaptive functions that can eventually interfere with the patient's ability to live independently. Dementia also constitutes of impairment in short- and long-term memory plus additional symptoms, such as problems with abstract thinking, judgment, or personality. An estimated 18 million patients suffer from dementia worldwide. The most common forms of dementia include Alzheimer's disease and vascular dementia. Other forms are frontotemporal dementia and Pick's disease.

Dementia can also be of vascular origin. Vascular dementia (atherosclerotic cerebrovascular disease) is considered to be the second most common dementia of late life, affecting approximately 10-15% of all cases. AD and vascular dementia can exist in isolation or together (mixed dementia). In vascular dementia, atherosclerotic changes in cerebral vessels can lead to reduced local blood flow that results in multiple small strokes (multi-infarct dementia). Vascular dementia is pharmacologically treated by stroke prophylaxis, and by treatment of the cognitive deficit.

Alzheimer's disease (AD), the most common and important form of dementia, is a neurodegenerative disorder that is characterized by progressive impairment of cognitive functions, such as abstract reasoning and memory. Currently, an estimated 2 million people in the United States and 12 million worldwide are afflicted by this disease. Due to increasing life expectancy, it is predicted that there will be over 100 million AD patients worldwide by the year 2050. AD is one of the most prevalent illnesses in the elderly. The majority of AD patients are in their sixties or older. More than 5% of all persons over the age of 70 have significant memory loss due to AD.

AD is mainly characterized through a gradual development of forgetfulness. In further advanced disease stages, other failures in cerebral function become increasingly apparent. This includes impairment of speech, writing, and arithmetic skills. Visiospacial orientation, such as parking the car, dressing properly, and giving and understanding directions to a location, can become defective or impaired. In late stage disease, patients forget how to use common objects and tools while retaining necessary motor power and co-ordination for these activities.

Schizophrenia is characterized by profound disruption in cognition and emotion, affecting the most fundamental human attributes: language, thought, perception, affect, and sense of self. Positive symptoms include psychotic manifestations, such as hearing internal voices or experiencing other sensations not connected to an obvious source (hallucinations) and assigning unusual significance or meaning to normal events or holding fixed false personal beliefs (delusions). Negative symptoms are characterized by affective flattening and lack of initiative or goals (avolition), loss of usual interests or pleasures (anhedonia), disturbances of sleep and eating, dysphoric mood (depressed, anxious, irritable, or angry mood) and difficulty concentrating or focusing attention.

Major depression is a multifaceted disorder characterized by primarily by dysphoric mood and loss of interest or pleasure in activities that were once enjoyable. Other physical and psychological symptoms include inability to concentrate, motor disturbances (psychomotor retardation or agitation), feelings of worthlessness, inappropriate guilt, thoughts of suicide, and disturbances in appetite and sleep.

Anxiety disorders are a group of syndromes that include generalized anxiety disorder, panic disorder, phobias, obsessive-compulsive disorder, and post traumatic stress disorder. Although each disorder has its own distinct features, all share common symptoms of excessive worrying, intense fears and dread, hypervigilance and/or somatic symptoms, in the absence of a dangerous situation.

Normal sexual function requires, among others, the ability to achieve and maintain penile erection. Major anatomic structures of the penis that are involved in erectile function include the corpus cavernosum, corpus spinosum, and the tunica albuginea (a collagenous sheath that surrounds each corpus). The corpora are composed of a mass of smooth muscle (trabecula) which contains a network of endothelial-lined vessels (lacunar spaces). Penile tumescence and erection is caused by relaxation of the arteries and corporal smooth muscles, while closing emissary veins, leading to increased blood flow into the lacunar network. Central and peripheral innervation contributes to regulation of the erectile response.

Erectile dysfunction (ED) may result from failure to initiate, fill, or store adequate blood volume within the lacunar network of the penis. Depending on the underlying dysfunction, ED may be vasculogenic, neurogenic, endocrinologic, diabetic, psychogenic, or medication-related.

ED affects 10-25% of middle-aged and elderly men, and has a profound impact on the well-being of affected men. It is currently treated using PDE5 inhibitors such as vardenafil, tadalifil, and sildenafil. Intraurethral alpostadil (prostaglandin El) may be used in patients that fail on oral agents. In addition, vacuum constriction devices (VCD) are a well-established, noninvasive therapy.

Female sexual dysfunction (FSD) is highly prevalent, age-related, and progressive. It affects 30 to 50% of women. FSD denotes a range of medical problems and is categorized according to disorders of (1) desire, (2) arousal, (3) orgasm and (4) sexual pain, and symptoms include diminished vaginal lubrication, pain and discomfort with intercourse, decreased arousal, and difficulty achieving orgasm. On a molecular level, vasoactive intestinal peptide (VIP), nitic oxide (NO), and sex hormones such as estrogens and androgens have been suggested to be important in female sexual function. Current treatment approaches include estrogen replacement therapy, methyl testosterone, PDE5 inhibitors such as sildenafil, the NO-donor L-arginine, prostaglandin El, phentolamine, and the dopamine agonists apomorphine.

Pharmacological Methods

I. In-Vitro Determination of Affinity to CB1/CB2-Receptors

a)

The in-vitro determination of the affinity of the inventive 4-substituted pyrazoline compounds to CB₁/CB₂-Receptors is carried out as described in the publication of Ruth A. Ross, Heather C. Brockie et al., “Agonist-inverse agonist characterisation at CB₁ and CB₂ cannabinoid receptors of L-759633, L759656 and AM630”, British Journal of Pharmacology, 126, 665-672, (1999), whereby the transfected human CB₁ and CB₂ receptors of Receptor Biology, Inc. are used. The radioligand used for both receptors is [³H]-CP55940. The respective parts of the description is hereby incorporated by reference and forms part of the present disclosure.

b)

Rat Cerebellum CB1 Binding

Binding affinity to CB1 receptor was evaluated according to a modification of the method described by Govaerts et al., Eur J Pharmac Sci 23, 233-243 (2004). The respective parts of the description is hereby incorporated by reference and forms part of the present disclosure.

Briefly, cerebellum from male wistar rats (250-300 g) were carefully dissected on ice and homogenates were prepared with Potter-Helveheim in a cold 50 mM Tris-HCl solution containing 5 mM MgCl₂, 1 mM EDTA and 0.25 M sucrose, pH 7.4. The suspension was centrifuged at 1,000×g for 5 minutes. The supernatants were collected and centrifuged 50,000×g for 15 minutes. The resulting pellets were then resuspended in Tris-HCl buffer without sucrose, homogenized and incubated for 15 min at 37° C. in an orbital shaker bath and centrifuged again at 50,000×g for 15 min. Pellets were weighted, resuspended in Tris-HCl buffer without sucrose, homogenized with Ultraturrax at 13,500 rpm for 3×5 seconds and alicuoted in 0.9 ml volumes in Eppendorf tubes. Alicuotes were centrifuged at 20,800×g for 5 minutes, supernatants discarded and pellets were frozen at −80° C. until use. Total protein concentration was determined using the Bio-Rad Lowry method based kit.

Competitive binding experiments were performed in presence of 1 nM [³H]-CP 55,940 in siliconized glass tubes containing 100 μg protein/tube resuspended in 1 ml final volume of 50 mM Tris-HCl, 5 mM MgCl₂, 1 mM EDTA, 0.5% (w/v) bovine serum albumin, pH 7.4. Compounds were present at various concentrations and the non specific binding was determined in the presence of 10 μM HU-210. After 1 hour incubation at 30° C., the suspension was rapidly filtered through 0.5% PEI pre-treated GF/B fiber filters on a 96-well harvester and washed 3 times with 3 ml ice-cold binding buffer without bovine serum albumin. Radioactivity on filters was measured with Wallac Winspectral 1414 counter by liquid scintillation in 6 ml Ecoscint H (National Diagnostics, U.K.). Assays were made in triplicates.

Binding data were analyzed by non-linear regression with the software GraphPad Prism Version 3.03.

II. In-Vivo Bioassay System for Determination of Cannabinoid Activity

Mouse Tetrad Model

Substances with affinity for cannabinoid receptors are known to produce a wide range of pharmacological effects. It is also known that intravenous administration of a substance with affinity for cannabinoid receptors in mice produces analgesia, hypothermia, sedation and catalepsy. Individually, none of these effects can be considered as proof that a tested substance has affinity for cannabinoid-receptors, since all of these effects are common for various classes of centrally active agents. However, substances, which show all of these effects, i.e. substances that are active in this so-called tetrad model are considered to have affinity for the cannabinoid receptors. It has further been shown that cannabinoid receptor antagonists are highly effective in blocking the effects of a cannabinoid agonist in the mouse tetrad model.

The tetrad model is described, for example, in the publication of A. C. Howlett et al, International Union of Pharmacology XXVII. Classification of Cannabinoid Receptors, Pharmacol Rev 54,161-202, 2002 and David R. Compton et al., “In-vivo Characterization of a Specific Cannabinoid Receptor Antagonist (SR141716A): Inhibition of Tetrahydrocannbinol-induced Responses and Apparent Agonist Activity”, J. Pharmacol. Exp. Ther. 277, 2, 586-594, 1996. The corresponding parts of the descriptions are hereby incorporated by reference.

Material and Methods

Male NMRI mice with a weight of 20-30 g (Harlan, Barcelona, Spain) are used in all of the following experiments.

Before testing in the behavioural procedures given below, mice are acclimatised to the experimental setting. Pre-treatment control values are determined for analgesia hot plate latency (in seconds), rectal temperature, sedation and catalepsy.

In order to determine the agonistic activity of the substance to be tested, the mice are injected intravenously with the substance to be tested or the vehicle alone. 15 minutes after injection, latency in hot plate analgesia is measured.

Rectal temperature, sedation and catalepsy are measured 20 minutes after injection.

In order to determine the antagonistic activity the identical procedure is used as for the determination of the agonistic effects, but with the difference that the substance to be evaluated for its antagonistic activity is injected 5 minutes before the intravenous injection of 1.25 mg/kg Win-55,212 a known cannabinoid-receptor agonist.

Hot Plate Analgesia

The hot plate analgesia is determined according to the method described in Woolfe D. et al. “The evaluation of analgesic action of pethidine hydrochloride (Demerol)”, J. Pharmacol. Exp. Ther. 80, 300-307, 1944. The respective description is hereby incorporated by reference and forms part of the present disclosure.

The mice are placed on a hot plate (Harvard Analgesimeter) at 55±0.5° C. until they show a painful sensation by licking their paws or jumping and the time for these sensations to occur is recorded. This reading is considered the basal value (B). The maximum time limit the mice are allowed to remain on the hot plate in absence of any painful response is 40 seconds in order to prevent skin damage. This period is called the cut-off time (PC).

Fifteen minutes after the administration of the substance to be tested, the mice are again placed on the hot plate and the afore described procedure is repeated. This period is called the post-treatment reading (PT).

The degree of analgesia is calculated from the formula: % MPE of Analgesia=(PT−B)/(PC−B)×100 MPE=Maximum possible effect. Determination of Sedation and Ataxia

Sedation and ataxia is determined according to the method described in Desmet L. K. C. et al. “Anticonvulsive properties of Cinarizine and Flunarizine in Rats and Mice”, Arzneim.-Forsch. (Frug Res) 25, 9, 1975. The respective description is hereby incorporated by reference and forms part of the present disclosure.

The chosen scoring system is

0: no ataxia;

1: doubtful;

2: obvious calmness and quiet;

3 pronounced ataxia;

prior to as well as after treatment.

The percentage of sedation is determined according to the formula: % of sedation=arithmetic mean/3×100 Hypothermia:

Hypothermia is determined according to the method described in David R. Compton et al. “In-vivo Characterization of a Specific Cannabinoid Receptor Antagonist (SR141716A) Inhibition of Tetrahydrocannbinol-induced Responses and Apparent Agonist Activity”, J. Pharmacol Exp Ther. 277, 2, 586-594, 1996. The respective description is hereby incorporated by reference and forms part of the present disclosure.

The base-line rectal temperatures are determined with a thermometer (Yello Springs Instruments Co., Panlabs) and a thermistor probe inserted to 25 mm before the administration of the substance to be tested. Rectal temperature is again measured 20 minutes after the administration of the substances to be tested. The temperature difference is calculated for each animal, whereby differences of ≧2° C. are considered to represent activity.

Catalepsy:

Catalepsy is determined according to the method described in Alpermann H. G. et al. “Pharmacological effects of Hoe 249: A new potential antidepressant”, Drugs Dev. Res. 25, 267-282. 1992. The respective description is hereby incorporated by reference and forms part of the present disclosure.

The cataleptic effect of the substance to be tested is evaluated according to the duration of catalepsy, whereby the animals are placed head downwards with their kinlegs upon the top of the wooden block.

The chosen scoring system is:

Catalepsy for:

more than 60 seconds=6; 50-60 seconds=5, 40-50 seconds=4, 30-40 seconds=3, 20-30 seconds=2, 5-10 seconds=1, and less than 5 seconds=0.

The percentage of catalepsy is determined according to the following formula: % Catalepsy=arithmetic mean/6×100 III. In Vivo Testing for Antiobesic Activity a) Accute Treatment

Normally handled rats were habituated to a reversed cycle 12/12 h, and the tested compound as well as saline was acutely orally administered. After administration the cumulated food intake (g) was measured at 6 h and 24 h. Following that the difference in body weight between control and compound treated animals was measured. This is a variation of the test according to Colombo et al. as described below.

b) Long-Term Treatment

The in-vivo testing for antiobesic activity of the inventive pyrazoline compounds is carried out as described in the publication of G. Colombo et al., “Appetite Suppression and Weight Loss after the Cannabinoid Antagonist SR 141716”; Life Sciences, 63 (8), 113-117, (1998). The respective part of the description is hereby incorporated by reference and forms part of the present disclosure.

IV. In Vivo Testing for Antidepressant Activity

The in-vivo testing for antidepressant activity of the inventive pyrazoline compounds in the water despair test is carried out as described in the publication of E. T. Tzavara et al., “The CB1 receptor antagonist SR141716A selectively increases monoaminergic neurotransmission in the medial prefrontal cortex: implications for therapeutic actions”; Br. J. Pharmacol. 2003, 138(4):544:53. The respective part of the description is hereby incorporated by reference and forms part of the present disclosure.

The present invention is illustrated below with the aid of examples. These illustrations are given solely by way of example and do not limit the general spirit of the present invention.

V. In Vitro Determination of Antagonism to CB1-Receptor

Membrane Preparation:

Chinese hamster ovary (CHO) cells stably expressing recombinant human cannabinoid 1 receptor (CB1) were cultured in nutrient mixture Ham's F 12 supplemented with 10% heat-inactivated fetal bovine serum, 2 mM L-glutamine, 50 U/ml penicillin, 50 U/ml streptomycin and 0.5 mg/ml geneticin. In order to obtain cells, culture flasks were washed twice with phosphate buffered saline and scraped. Then, cells were collected by centrifugation (200×g, 10 min) and stored dry at −80° C. Cells were homogenized in ice-cold 20 mM HEPES, 10 mM EDTA (pH 7.5) and centrifuged at 40,000×g for 15 min at 4° C. The pellet was resuspended in 20 mM HEPES, 0.1 mM EDTA (pH 7.5) and centrifuged for 15 min at 4° C. The final pellet was resuspended in 20 mM HEPES, 0.1 mM EDTA (pH 7.5), and divided in aliquots and stored at −80° C. until use.

[³⁵S]GTPγS Binding Assay:

The reaction was performed in 96-well plates. Membranes (15 μg protein/well) were incubated for 60 min at 30° C. in buffer (50 mM HEPES, 100 mM KCl, 5 mM MgCl₂, 1 mM EDTA, 0.1% wt/vol bovine serum albumin, 5 μM GDP, saponin (10 μg/ml), 0.5 nM [³⁵S]GTPγS, pH 7.4) with compound at 1 μM final concentration in either the absence or presence of dose response curve of agonist WIN 55, 212-2 between 3 nM and 3 μM. The incubation was terminated by rapid filtration through Millipore Multiscreen glass fiber FB, and rinsed two-times with ice-cold assay buffer. Filter plates were dried and 30 μl of scintillation liquid was added. Radioactivity was determined using Wallac Microbeta Trilux. Each experiment was performed at least in duplicate. A WIN 55, 212-2 dose-response either alone or in the presence of Rimonabant (1 μM) was systematically performed.

Calculations:

The average of basal [³⁵S]GTPγS binding was subtracted from all binding data. In order to compare the antagonism results from one screening campaign to another one, the difference between the maximal agonist effect of WIN 55, 212-2 alone, and the maximal antagonism effect due to WIN 55, 212-2 plus Rimonabant (1 μM) was defined as 100%.

Further Methods:

Alcohol Intake

The following protocol may be used to evaluate the effects of alcohol intake in alcohol preferring (P) female rats (e.g. bred at Indiana University) with an extensive drinking history. The following reference provides detailed a description of P rats: Lumeng, L, et al., “Different sensitivities to ethanol in alcohol-preferring and -nonpreferring rats,” Pharmacol, Biochem Behav., 16, 125-130 (1982).

Female rats are given 2 hours of access to alcohol (10% v/v and water, 2-bottle choice) daily at the onset of the dark cycle. The rats are maintained on a reverse cycle to facilitate experimenter interactions. The animals are initially assigned to four groups equated for alcohol intakes: Group 1-vehicle; Group 2-positive control (e.g. 5.6 mg/kg AM251; Group 3-low dose test compound; and Group 4-high dose of test compound. Test compounds are generally mixed into a vehicle of 30% (w/v)—cyclodextrin in distilled water at a volume of 1-2 ml/kg. Vehicle injections are given to all groups for the first two days of the experiment. This is followed by 2 days of drug injections (to the appropriate groups) and a final day of vehicle injections. On the drug injection days, drugs are given sc 30 minutes prior to a 2-hour alcohol access period. Alcohol intake for all animals is measured during the test period and a comparison is made between drug and vehicle-treated animals to determine effects of the compounds on alcohol drinking behavior.

Additional drinking studies can be done utilizing female C57Bl/6 mice (Charles River). Several studies have shown that this strain of mice will readily consume alcohol with little to no manipulation required (Middaugh et al., “Ethanol Consumption by C57BU6 Mice: Influence of Gender and Procedural Variables” Alcohol, 17 (3), 175-183, 1999; Le et al., “Alcohol Consumption by C57BL/6, BALA/c, and DBA/2 Mice in a Limited Access Paradigm” Pharmacology Biochemistry and Behavior, 47, 375-378, 1994).

For example, upon arrival mice are individually housed and given unlimited access to powdered rat chow, water and a 10% (w/v) alcohol solution. After 2-3 weeks of unlimited access, water is restricted for 20 hours and alcohol is restricted to only 2 hours access daily. This is done in a manner that the access period was the last 2 hours of the dark part of the light cycle.

Once drinking behavior is stabilized, testing can commence. Mice are considered stable when the average alcohol consumption for 3 days is 20% of the average for all 3 days. Day 1 of test consists of all mice receiving vehicle injection (sc or ip). Thirty to 120 minutes post injection access is given to alcohol and water. Alcohol consumption for that day is calculated (g/kg) and groups are assigned so that all groups have equivocal alcohol intake. On day 2 and 3, mice are injected with vehicle or drug and the same protocol as the previous day is followed. Day 4 is wash out and no injections are given. Data is analyzed using repeated measures ANOVA. Change in water or alcohol consumption is compared back to vehicle for each day of the test. Positive results would be interpreted as a compound that was able to significantly reduce alcohol consumption while having no effect on water

Oxygen Consumption Methods:

Whole body oxygen consumption is measured using an indirect calorimeter (Oxymax from Columbus Instruments, Columbus, Ohio) in male Sprague Dawley rats (if another rat strain or female rats are used, it will be specified). Rats (e.g. 300-380 g body weight) are placed in the calorimeter chambers and the chambers are placed in activity monitors. These studies are done during the light cycle. Prior to the measurement of oxygen consumption, the rats are fed standard chow ad libitum. During the measurement of oxygen consumption, food is not available. Basal pre-dose oxygen consumption and ambulatory activity are measured every 10 minutes for 2.5 to 3 hours. At the end of the basal pre-dosing period, the chambers are opened and the animals are administered a single dose of compound (the usual dose range is 0.001 to 10 mg/kg) by oral gavage (or other route of administration as specified, i.e., sc, ip, iv). Drugs are prepared in methylcellulose, water or other specified vehicle (examples include PEG400, 30% beta-cyclo dextran and propylene glycol). Oxygen consumption and ambulatory activity are measured every 10 minutes for an additional 1-6 hours post-dosing.

The Oxymax calorimeter software calculates the oxygen consumption (ml/kg/h) based on the flow rate of air through the chambers and difference in oxygen content at inlet and output ports. The activity monitors have 15 infrared light beams spaced one inch apart on each axis, ambulatory activity is recorded when two consecutive beams are broken and the results are recorded as counts.

Resting oxygen consumption, during pre- and post-dosing, is calculated by averaging the 10-min02 consumption values, excluding periods of high ambulatory activity (ambulatory activity count >100) and excluding the first 5 values of the pre-dose period and the first value from the post-dose period. Change in oxygen consumption is reported as percent and is calculated by dividing the post-dosing resting oxygen consumption by the pre-dose oxygen consumption *100. Experiments will typically be done with n=4-6 rats and results reported are mean+/−SEM.

Interpretation:

An increase in oxygen consumption of >10% is considered a positive result. Historically, vehicle-treated rats have no change in oxygen consumption from pre-dose basal.

Nicotine Dependence

An intravenous nicotine self-administration model or place preference model may be used to assess the effects of a test compound on nicotine dependence (see, e.g., Vastola, et al. Physiol. Behav. 77:107-114, 2002; Brower, et al., Brain Res. 930:12-20, 2002).

Place Preference

Sprague-Dawley rats are used in this study (Vastola, et al., 2002). Animals are housed in a temperature-controlled, 12 h/12 h illumination cycle with ad libitum access to food and water. Conditioning and testing are conducted in a chamber divided into two compartments with a door separating the two compartments. Behavior of the animals is recorded by video camera.

Animals are habituated to the injection procedure for several days. The animals are then placed into the test chamber and given free access to both compartments. The initial preference for a particular compartment is determined. For the conditioning trials, animals are injected with nicotine and restricted to the nonpreferred compartment, or the animals are injected with saline and restricted to the preferred compartment. On test day, the door separating the compartments is removed, the animal is placed in the center of the chamber and allowed to move freely between compartments. Time spent in each compartment is scored. Preferential occupancy of is the nicotine compartment follows from the conditioned reinforcing effects of nicotine.

Self-Administration

Self-administration in animals is a predictor of a compound's abuse potential in humans. Modifications to this procedure may also be used to identify compounds that prevent or block the reinforcing properties of drags that have abuse potential. A compound that extinguishes the self-administration of a drag may prevent that drag's abuse or its dependence.

Sprague-Dawley rats are used in this study. Initially, animals are housed in a temperature-controlled, 12 h/12 h illumination cycle with ad libitum access to food and water. The animals are then implanted with jugular catheters which exit through the animal's back, and each animal is placed in an individual operant chamber (Brower, et al., 2002). The catheters are connected to a computer-driven syringe pump which is located outside of the chamber. The chamber contains two levers with a green light located above each lever. The light is illuminated when nicotine is available.

In a self-administration test, animals are placed in the operant chambers and the levers are randomly designated as an active and inactive lever. Each response on the active lever produces an infusion of nicotine. Presses on the inactive lever have no effect, but are also recorded. Animals are then trained to self-administer nicotine over a set period of time by having drag access during each daily session. Illumination of the chamber house light signals the beginning of the session and the availability of nicotine. When the session ends, the house light is turned off. Initially, a nicotine infusion occurs with every press of the active lever. Once lever-pressing behavior has been established, the number of presses to produce a nicotine infusion is increased. After stable nicotine self-administration is obtained, the effect of a test compound on the nicotine-reinforced behavior may be evaluated. Administration of this test compound prior to the session can either potentiate, extinguish, or produce no change to the self-administrating behavior. Tests are conducted every two days, and the order of the administration of the test compound doses is controlled.

Alzheimer/Dementia Experiments

Morris Water Maze Task

The Morris water maze is a behavioral in vivo test to measure spatial orientation learning and memory through a complex learning task. It is highly suitable for testing compounds that enhance learning and memory. A circular water tank or pool (diameter 2 m, height 0.7 m) is filled with water, and a 10 cm2 platform is placed 1-1.5 cm below the water surface at a defined location within the pool. The escape platform is not visible for an animal swimming in the water tank. For the experiment, a rat or mouse is placed into the pool to swim freely.

The animals have the task to localize the submerged platform, and the time and distance required for successful retrieval is measured. Multiple extra-maze cues are provided by the furniture in the room, including desks, computer equipment, a second water tank, the presence of the experimenter, and by a radio on a shelf that is playing softly.

Before administration of the test compound, animals are usually trained in the task 4 times a day for 5 days. Test compounds are administered orally or intraperitoneally on the day of the experiment at a defined time (e.g., 30 minutes before the first swim test). Control animals are dosed with the corresponding vehicle not containing test compound. Active compounds yield shorter times and distances to localize the platform (i.e., the better the animal remembers the location of the platform, the shorter the distance covered and the faster the platform is reached).

The test can also be carried out using transgenic or cognitively impaired animals. Cognitive impairment is induced either by old age or experimentally through brain lesions, such as bilateral lesions of the entorhinal cortex in rats. Such lesions can be induced by intracerebral injections of the excitotoxin ibotenic acid.

Object Recognition Task

The object recognition task is used to assess the effects of compounds on the cognitive performance of rodents. A rat is placed in an open field, in which two identical objects are located. The rats inspects both objects during the initial trial of the test. After a certain retention interval (e.g., 24 hours), a second trial is carried out. Here, one of the two objects used in the first trial (the ‘familiar’ object) and a novel object are placed in the open field, and the inspection time at each of the objects is measured. Good retention is reflected by higher exploration times towards the novel compared with the ‘familiar’ object.

Administration of the putative cognition enhancer prior to the first trial predominantly allows assessment of the effects on acquisition, and on the consolidation processes. Administration of the test compound after the first trial allows to assess the effects on consolidation processes, whereas administration before the second trial allows to measure effects on retrieval processes.

Passive Avoidance Task

The passive avoidance task assesses memory performance in rats and mice. The inhibitory avoidance uses an apparatus consisting of a box with two compartments separated by a guillotine door that can be operated by the experimenter. One compartment is illuminated with bright light, and the other compartment is dark. A threshold of 2 cm separates the two compartments when the guillotine door is 15 raised. When the door is open, the illumination in the dark compartment is about 2 lux. The light intensity is about 500 lux at the center of the floor of the light compartment.

Two habituation sessions, one shock session, and a retention session are given, separated by inter-session intervals of 24 hours. During the habituation sessions and the retention session, the rat is allowed to explore the apparatus for 300 seconds. The rat is placed in the light compartment, facing the wall opposite to the guillotine door. After an accommodation period of 15 seconds, the guillotine door is opened so that all parts of the apparatus can be visited freely. Rats normally avoid brightly lit areas and will enter the dark compartment within a few seconds.

In the shock session, the guillotine door between the compartments is lowered as soon as the rat has entered the dark compartment with all paws, and a scrambled 1 mA footshock is administered for 2 seconds. Then the rat is removed from the apparatus and returned into its home cage. The procedure during the retention session is identical to that of the habituation sessions.

The step-through latency, that is, the first latency of entering the dark compartment (in seconds) during the retention session is an index of the memory performance of the animal: a better retention is assumed if the latency to enter the dark compartment is longer. A test compound is given 30 minutes before the shock session, together with 1 mg/kg scopolamine. Scopolamine impairs the memory performance during the retention session 24 hours later. If the test compound increases the enter latency compared with the scopolamine-treated controls, it is considered to possess cognition enhancing activity. T-maze Spontaneous Alternation Task

The T-maze spontaneous alternation task (TeMCAT) assesses the spatial memory performance in mice. The start arm and the two goal arms of the T-maze are provided with guillotine doors that can be operated manually by the experimenter. A mouse is put into the start arm at the beginning of training. In the first trial, either the left or right goal arm is blocked by lowering the respective guillotine door (forced trial).

After the mouse has been released from the start arm, it will explore the maze, eventually entering the open goal arm, and return to the start position, where it will be confined for 5 seconds, by lowering the guillotine door. Then, the animal can choose freely between the left and right goal arm (all guillotine-doors opened) during 14 additional trials (free choice trials). As soon as a mouse has entered one goal arm, the other arm is closed. The mouse eventually returns to the start arm and is free to visit whichever arm it wants after having been confined to the start arm for 5 seconds. After completion of 14 free choice trials in one session, the animal is removed from the maze.

Out of the 14 trials the alternations in percent are calculated. This percentage and the total time needed to complete the first forced trial and the subsequent 14 free choice trials (in seconds) is analyzed. In addition, cognitive deficits can be induced by injection of scopolamine 30 minutes before the start of the training session. A cognition enhancer, administered before the training session, will at least partially, antagonize the scopolamine-induced reduction in the spontaneous alternation rate.

Depression Model

A forced swim or tail suspension model may be used to assess the efficacy of antidepressant compounds (see, e.g., Porsolt, et al., Nature 266:730-732, 1977; Stem, et al., Psychopharmacology 85:367-370, 1985).

Forced Swim Test

Rats or mice are placed in a cylinder filled with water 23-25° C. from which no escape is possible. Initially, animals struggle and try to escape, but eventually adopt a characteristic immobile posture and make no further attempts to escape except for small movements needed their head above water. Animals are dosed with a compound and the activity (swimming or climbing) or immobility is measured by an observer. The immobility is considered by some to reflect a ‘behavioral despair’ in which animals cease to struggle to escape the aversive situation. A wide variety of clinically used antidepressants (TCAs, MAOs, SSRIs, atypicals) decrease immobility in this test and has a good predictive validity in that it detects antidepressants with different mechanisms of action but its construct validity is weak. At least two distinct active behavioral patterns are produced by pharmacologically selective antidepressant drugs. Serotonin-selective reuptake inhibitors increase swimming behavior, whereas drugs acting primarily to increase extracellular levels of norepinephrine or dopamine increase climbing behavior. There are false positives (psychostimulants) but relatively few false negatives ([beta]-adrenergic agonists). The test is sensitive to muscle-relaxant (benzodiazepines) and sedative (neuroleptics) effects, leading to enhanced immobility. False positives and false negatives can often be screened by measuring if the compound produces locomotor stimulation or sedation.

Tail Suspension Test

When suspended by the tail, mice will initially struggle and try to escape and then alternate between active escape attempts and immobililty. In this test, animals are dosed with a compound and the immobility is measured by an observer for 6 min. Porsolt describes the immobile behavior as ‘behavioral despair’ which animals cease to struggle to escape the aversive situation. A large variety of clinically antidepressants (tricyclics, MAOs, SSRIs, and atypicals) reduce immobility in this model. The test has a good predictive validity for antidepressant activity and works for most antidepressant classes including but has some false positives (psychostimulants). The test is sensitive to muscle-relaxant (benzodiazepines) and sedative (neuroleptics) effects, which lead to enhanced immobility. False positives and false negatives can often be screened by measuring if the compound produces locomotor stimulation or sedation. Strain differences in the tail suspension test have been found in mice. The tail suspension test has some face validity but its construct validity is rather weak.

Schizophrenia Model

A prepulse inhibition model may be used to assess the efficacy of antipsychotic compounds (see Swerdlow and Geyer, Schizophrenia Bulletin 24: 285-301, 1998).

Prepulse Inhibition

Prepulse inhibition is the process whereby a relatively mild stimulus, the prepulse, suppresses the response to a strong, startle-eliciting stimulus when the prepulse precedes the startle stimulus by a brief duration (about 10 to 500 milliseconds). Prepulse inhibition is a cross-species phenomenon (ie, it is present in mammals ranging from mice to humans), yet it is relatively absent among schizophrenic patients. The deficit in PPI in schizophrenic patients is thought to reflect the loss of sensorimotor gating that may lead to sensory flooding and cognitive fragmentation. In this test, mice or rats are administered compounds and individually placed into a holder on a transducer platform to measure whole body startle. The holder is housed in a startle chamber with background white noise. Following a brief habituation period, animals are given multiple trials of a weak auditory prepulse stimulus, is followed by a strong auditory startle stimulus. Four types of trials are given: prepulse plus startle, prepulse alone, startle alone, and no stimulation. PPI is measured as the amount of inhibition of startle following the prepulse and is expressed as the percentage of basic startle. As a control, measurements are taken in the no stimulation and prepulse alone trials. PPI is considered a test with good predictive, face and construct validity for schizophrenia. Putative antipsychotics can be tested alone to determine if they enhance PPI. Alternately, antipsychotics can be screened to determine if they block various agents that disrupt PPI (apomorphine, d-amphetamine, PCP, ketamine, DOI). Finally, mutant mice with or without drugs can be screened using the PPI procedure.

Anxiety Model

An elevated plus maze model may be used to assess the efficacy of anxiolytic compounds (see Pellow and File, Pharm. Biochem. Behav. 24, 525-529, 1986).

Elevated Plus Maze

The elevated plus maze is widely used as an anxiety paradigm that examines the conflict between the drive to explore and the aversiveness of heights and open spaces of rats or mice. The maze is a cross made up of two open and two closed arms that is raised above the ground. The combination of light, the open arms, and the height is thought to produce unconditioned fear or anxiety responses in mice or rats. The test apparatus is an open top maze constructed of opaque plastic with alternating open and enclosed arms. For rats, each arm is 45-55 cm long and 8-12 cm wide, with the sides of the enclosed arms 35-45 cm high, the juncture approximately 10×10 cm, and the maze is elevated 45-55 cm above the floor. The mouse elevated plus maze consists of two closed arms (15×6×30 cm) and two open arms (1×6×30 cm) forming a cross, with a quadrangular center (6×6 cm). The maze is placed 50 cm above the floor. Testing is performed in a room free of noise and distraction. On test days animals are administered drug or vehicle. If a pretreatment period is necessary, the animals are returned to the home cage for the duration of the pretreatment time; otherwise, the animals are placed in a clear plastic holding chamber singly or with cage mates for 1-10 minutes prior to test time. Rats are then placed in the center of the maze always oriented in the same direction, either consistently facing an open arm or an enclosed arm. For 5-10 minutes, entries into each arm and the time spent in each arm are recorded by the observer(s) or by videotape or a computer receiving input from a video camera mounted above the maze. To count as an entry, all four paws must be inside the arm. If necessary, additional measures of anxiety-related behaviors will be recorded, i.e., time spent motionless, time spent in the center, time spent grooming, and the number of rears, stretching postures or feces produced. Following testing the animals are returned to the home cages. When animals are placed in the center of the maze, they spend most of their time in the closed arms, avoiding the open arms. Anxiolytic drugs, such as benzodiazepines, will increase the amount of time animals spend in the open arms. The test is also sensitive to anxiogenic drugs, which lends strong support for its predictive validity.

Erectile Dysfunction

Drugs affecting erectile function may be tested by measuring the effect on apomorphine-evoked increases in intracavernous pressure in the awake rat as described by Andersson, et al., (J. Urol. 161:1707-17]2, 1999). One end of a polyethylene tubing is implanted into the cavernosal space of the penis of male Sprague-Dawley rats. After recovery from the surgery, intracavernous pressure is recorded using a pressure transducer connected to a multichannel pen-recorder. Erections are induced by administration of apomorphine (100-250 ug/kg s.c.) with or without test compound, and the results are compared for the treated group and the non-treated group.

Female Sexual Dysfunction

Systems to test compounds for the treatment of female sexual dysfunction include in vitro and in situ models using vaginal or clitoral smooth muscle preparations, histological evaluation, and vaginal blood flow assessments. In vivo studies of sexual responses focus on behavioral paradigms involving lordotic posturing and receptivity, as well as indices of motivation using a dual chamber pacing method (see, e.g., Hale, et al., Int. J. Impot. Res. 15 Suppl 5: S75-79, 2003).

The present invention is illustrated below with the aid of examples. These illustrations are given solely by way of example and do not limit the general spirit of the present invention.

EXAMPLES Preparation of Compounds of General Formula IVa

A suspension of a compound of general formula III (1 equivalent) in glacial acetic acid (40 equivalents) was heated at 80° C. under nitrogen atmosphere. When the suspension became a solution, a solution of acid of general formula IIa (1 equivalent) in acetic acid (20 equivalents) was added and the solution was left stirring at 80° C. for 2 h. The reaction mixture was allowed to crystallise at 0-4° C. overnight after partial evaporation of acetic acid. The beige solid formed was filtered off under vacuum through a sintered funnel (porosity 4) and washed several times with water. This crystallization process led to the major diastereomeric acid with cis configuration. The yield range for the cyclization with hydrazine to obtain the main diastereomer was around 46-80%.

The reaction mixture can also be cooled down to room temperature and poured through an addition funnel into water which is cooled in an ice bath with magnetically stirring. The addition must be slow and at least double volume of water per volume of acetic acid is required. A precipitate should form, but in the case a gum starts to form, it should be filtered and the rest of the material should be poured into another large volume of water. The solid obtained is suspended in water several times and filtered off until the pH of the water was above 3. This solid also corresponds to the cis form.

Alternatively, the dark mixture can be extracted with dichloromethane washed thoroughly with H₂O, dried over Na₂SO₄ and evaporated to dryness. Recrystallisation of the crude material from toluene (3 to 4 mL of toluene per gram of material) allows the recovery of the major diastereomer with cis configuration.

Preparation of Compounds of General Formula Va

A compound of general formula IVa (15 mmol) was dissolved in 120 mL of dry toluene and thionyl chloride (18 mmol) was added. The mixture was heated to 80° C. for 2.5 hours. The solvent was removed under reduced pressure and the resulting crude residue was used without any further purification.

Preparation of Compounds of General Formula Ic

A compound of general formula R³—H (5.6 mmol) and triethylamine (4 mL) were dissolved in dichloromethane (25 mL) under nitrogen atmosphere. The resulting mixture was cooled to 0° C. and a solution of a compound of general formula Va (4.6 mmol) in dichloromethane (15 mL) was added dropwise. The resulting reaction mixture was stirred at room temperature (approximately 25° C.) overnight, washed with water, saturated aqueous solution of sodium bicarbonate and again with water, dried over sodium sulfate, filtered and evaporated to dryness in a rotavapor. The residue was crystallized from ethanol, ethyl acetate or acetone. The crystallized solid was removed via filtration and the mother liquors were concentrated to yield a second fraction of crystallized product. The two fractions were combined to give the desired product (yield range: 60-80%). Alternatively, a solution of 2 N HCl in diethyl ether or 2.8 N in ethanol was added to form the respective hydrochloride, which was collected by filtration.
